Sony VGN-AW190J Power Adapter
If buying off-brand, make note of both the voltage and amperage output. Upon choosing a replacement charger, choosing the Sony brand one is always going to be the safest and easiest way to go. The Sony VGN-AW190J power adapter has two main uses, to charge any and all batteries while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that can be used on other units, make sure you check the part number for the correct one. A universal power adapter is another possibility if you absolutely need to.
How do you know when your AC adapter has gone bad?
- The unit will not run while solely using the AC adapter
- Battery does not charge completely
- The majority of Sony power chargers will get very warm to the touch when they are plugged in for a period of time
